for my main computer... I am on newest Windows 10 1803 which is build 17134.137 and I got no issues. but I don't use Chrome as I use Firefox.
my backup computer (i.e. HP DV5-1002nr laptop (which apparently was new in 2008(I got it used for barely any $ late last year))) is running Linux Mint v19 (Xfce) which was recently released. Mint only requires 1GB of RAM but 2GB is recommended for comfortable usage and I got 3GB in my laptop although only about 2.75GB is usable for the system as I am assuming some of that RAM is shared with the GPU. with my light use I don't seem to crack about 50% of RAM usage tops which probably means I am not using all that much over 1GB of RAM as that was with Firefox with a handful of tabs and some other odds and ends open.
p.s. on a side note... my main computer I have now (i3-2120 CPU with 8GB of RAM etc) is about to be the longest I had a computer for without upgrading the core components as the previous title holder was from March 2006 til May 2012, so 6 years and 2 months. but my current one is from May 2012 to July 2018 and counting which is also 6 years and 2 months. so next month it will take the record for longest PC I ever owned.
basically all of my computers I ever owned...
1995 = Intel 486DX2 66Mhz (Packard Bell brand)
1996 = Intel Pentium 133Mhz (Packard Bell brand)
2000 = Intel Celeron 500Mhz (Emachines brand) (recently dumped this in the trash earlier this year and someone must have taken it before the trash guys got it)
2001 = AMD Athlon 1.2Ghz (Alienware brand) (I still have this one but I won't be surprised if this gets dumped eventually)
2006 = AMD Athlon 3500+ (custom built) (which is a single core CPU. but I upgraded CPU in 2010 for Mafia II to a AMD Athlon X2 3600+ 2.0Ghz)
2012 to date = Intel i3-2120 (custom built)
with that said I have upgraded components like the GPU (graphics card) here and there with those computers as the first good graphics card I ever had was a 3DFX Voodoo 4MB (under 'Diamond Monster 3D' brand) which I still have that GPU to this day. the computer from 2000 had some 3DFX Voodoo 3 2000 and 3000 16MB cards at one point. the one from 2001 originally came with a Geforce 2 GTS 32MB but was eventually upgraded to a Geforce 3 Ti 200 64MB. then the computer from 2006 I originally put a Geforce 7900 GT 256MB card in it which was eventually upgraded to a Radeon 5670 512MB at the time I upgraded the CPU for Mafia II (2010). then for the 2012 computer, which is using the same case as the one from 2006, I just swapped out the motherboard/CPU/RAM and used that same Radeon 5670 512MB GPU until July 2017 and now have my current Geforce GTX 1050 Ti 4GB. plus, I had to change out some PSU's (power supplies)... like one time on the computer from 2001 (along with a dead hard drive), then one on the computer from 2006, and once in the one I had from 2012. my current PSU is the longest lasting one I had to date which is not surprising because it's the highest quality and the longest warranty as it had a 5 year warranty but it expired in Nov 2017 I think. hopefully my luck changes with this current PSU as usually not too long after warranty ends the PSU has died on me in the past as ones in the last typically had either a 2 or 3 year warranty. but based on what I was reading back when I got my current PSU they tend to have some of the lowest failure rates which is under the Seasonic brand.
No one can blame MS for that because... Pentium III's don't even have SSE2 support which current web browsers require and have for roughly a couple of years now as Firefox dumped support of CPU's without SSE2 sometime in 2016 I think so the browsers simply won't work on those CPU's, at all.
so lack of Windows 7 support is the least of their problems as those computers are basically useless without SSE2 support in the CPU since you can't use current web browsers as Firefox started requiring SSE2 in the CPU about a couple of years ago which was the nail in my old PC's coffin from 2001 which has a Athlon 1.2Ghz CPU (it's currently got 1GB of RAM in it which would run Linux okay enough but even that's pretty much shot because the lack of SSE2) although even back before browsers dumped CPU's without SSE2, it was still quite slow as loading basic web pages really taxed the CPU (like you could tell the CPU was noticeably slowing load times) and ones that were a little graphics heavy really taxed it so it was pretty much dead anyways (even though technically it worked for very basic browsing functionality if you got patience).
but it's funny in a way because at the time (in 2001 or so) that CPU (my Athlon 1.2Ghz) beat Intel Pentium 4 CPU's roughly twice those Ghz (say 2.4Ghz or so) in gaming if I recall correctly (basically AMD's CPU's were ahead of Intel CPU's in gaming until the 'Core 2 Duo' in about mid-2006). but since those Pentium 4's have SSE2 support and the Athlon I got does not, my ancient computer is now useless (for about a couple of years now) where as Pentium 4's can still be used even if they are slow.
EDIT: apparently there are some browsers that will work on SSE only CPU's, as someone I was talking to on another forum earlier mentioned a custom Pale Moon 32bit that works on SSE CPU's (the one he linked to was for Linux) but these are not the mainstream or even semi-mainstream and it appears one would have to manually check for updates for it etc. so I guess while it might be technically possible to use modern browsers on SSE CPU's, overall it's probably not worth it especially given how ancient/slow those SSE only CPU's tend to be at this point in time.
